SPOOL-BEARING BRACKET FOR YARN-TUBE FRAMES.

vApplication filed. 511116.30, 1922. SerialiNo. 571,853.

To .all 'e0 llo-m it may concern Be it known that I, rErrA H. RYON, `a citizen of the United States, residing at lValtham, in the eountyof Middlesex and State Aof lvassa'chusetts, Vhave invented a newV and useful Spool-Bearing Bracket for `Yarn- Tube Frames, of `which `the following is 'a specification.

This invention relates to yarntube frames =as.co1nmonly usedcin large Ynumbers infrnoquette looms. lily invention is particularly directed to theprovision `ofaniimprovedV bearing bracket for.` supporting the yarn spool on the tubeI frame andalso for attaching theassembled spool'andi tube frame to the pattern chain.

It isthe general object of my .invention to provide a forni of bearing bracket which is simple in construction, economical -inmanufacture and which possesses important `mechanical ,advantages whichv will be hereinafter described andjmore particularly'pointed out in the appended claims.

Two formsof my invention arevshown in the drawings, in which Fig. 1 isanfend view of one form of my improved construction; i

lFig. 5v is a plan view of the blank from along which this form of' my improved bracket is hook through the slot 23.

made; and

Fig. 6` is a sectional modification.

Referring to the drawings, I have shown a portion of a spool 10 and rectangular tube frame 11 to which the yarn tubes 12 are secured, these parts being of a usual form.

My improved spool bearing bracket is preferably formed from a single piece of sheet metal, as shown in Fig. 5, and comprises a body having a bearing portion 15, side portions 16 and a bottom portion 17. The bearing portion 15 is formed by partially severing the same from the surrounding metal which is thereafter bent outward, as shown in Fig. 2, to form an attaching portion 18 adapted toproject between the links 19 of the usual pattern chain on which the assembled yarn spools and tube frames are transported. The bearing portion 15 is side l elevation of a preferably bent inward, as also shown inA Fig.

.2, and is providedwitha hole` to'receive the are bent at right angles tov thebody of. the

bracket and are adapted to'extend intoiand lit closely within the end ofthe rectangular tube 11. One or more of these -portions16 and 17 may be threaded fat 21 to receive.

screws 22 by which the bracket isheld'V from displacement in the tube. The parts 16 and 17 are preferablydepressed around the threaded holes 21, thus affording more rooin` for the countersunk heads of the screws 22,.as the walls of the tube 11 are formed of. relatively thin metal.

A narrow slot 23 is formed in thebody ofthe bracket to receiveI the lower end 24 of a hook 25 by which the tube frame and spool are secured to the chain .links 19. 4The hook itself is preferably struck up orotherwise thickened and is curved along its lower edge as shown in Fig. 1, this curved edge permitting easy swinging movement of the brackets on vthe supporting chain.

The lower end 211 of theI hook is preferably formed substantially as shown in sec- 1 tion in F ig..2, with a U-shaped bend 261con- The` meeting the end` 24 to the hook 25. portion 27 of the bracket body directly below the slot 23 is preferably slitted at the sides so that it may be bent outward to the position shown in dotted lines `in Fig. 2 .to permit the insertion of the lower end of the The portion 27 is then bent backward tov normal position and the proportions of 'the lower end of the hook are such lthat it cannot thereafter be displaced from .the-bracket, so long as the part 27 remains in its normal position.

A spot or lug 28 may be formed at the extreme inner end of the part 24, co-operating with a similar spot or lug 29 on the bottom portion 17 to hold a spring 30 in position to press the hook 25 outward against the attaching portion 18.

It will be noted that the parts 16 are joined to the body by curved corner portions 31 which form wings or guides in the finished brackets along both sides of the friction pad 32 which is yieldingly pressed against the head of the spool 10 by a spring 33. These wings or guides 31 prevent lateral displacement of the friction pad and permit the spring 33 to be secured to the tube 11 by a single fastening only.

In Fig. 6 I have shown a slight modification in which the spool supporting member 35 is formed as a separate element Welded or otherwise secured to the body of the bracket and having a portion 36 extending within the tube 1l and closely fitting against the top plate thereof. Also in this modification I have shown the bracket secured in the tube by screws 37 through the top and bottom of the tube. With this construction it is possible to omit the side portions 16 if so desired.

From this foregoing description, it will be seen that I have provided a spool bearing bracket which may be very easily and cheaply constructed of sheet metal and in which all parts are of adequate strength `and are not easily damaged or displaced. In particular,vthe rigid hook 25 and coil spring 30 are much more dependable than the fia-t spring hook heretofore used.

Having 4thus described my invention, I

do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what I claim is l. In a tube frame, a hollow tube, a spool bearing bracket formed of a single piece of sheet metal and having integral side and bottom supporting portions adapted to project within said tube, and means to secure said bracket in position.

2. In a tube frame, a hollow tube, a spool bearing bracket formed of a single piece of sheet metal, said bracket having a bearing portion and having side and bottom supporting portions extending within said tube by which said bracket may be secured in operative position in the tube, and means to secure said parts together.

3. In a loom, a pattern chain, a supporting tube, a spool bearing bracket comprising a chain engaging portion, a bearing portion, and side and bottom portions by which said bracket may be secured in operative position in the tube, andi means to secure said bracket in position, all parts of said bracket being formed of a single piece of sheet metal.

4. In a loom, a supporting tube, a spool,

a sheet metal bearing bracket for said spool mounted on said tube, an elongated flat friction spring also mounted on said tube and yieldingly engaging the `periphery of the spool head, and integral projections` on said bearing bracket disposedat each side of the free end of said spring and preventing lateral displacement thereof.

5. In a loom, a pattern chain, a supporting tube, ay spool bearing bracket secured thereto and having a relatively narrow slot therein, a cha-in engaging hook having an offset portion extending through saidl slot and within said tube, and a spring to press said offset portion yieldingly against the upper inner wall of the tube.

6. In a loom, a pattern chain, a supporting tube, a spool bearing bracket having a rela-tively narrow slo-t therein, a chain engaging hook having an offset portion ex-v tending through said slot and within said tube, and a spring to press said offset por'- tion yieldfingly against the upper inner wall of the tube, said-bracket having a portion below said slot yadapted to be bent voutward to permit insertion of said hook.

7. In a loom, a pattern chain, a supporting tube, a spoo-l bearing bracket secured thereto, a substantially rigid chain engaging hook pivotally `connected to said bracket and having a portion extending within said tube, and a spring in said tube for said hook.

8. In a loom, a pattern chain, a supporting tube, a spool bearing bracket secured thereto, a substantially rigid chain engaging hook pivotally connected to said bracket and having a portion extending within said tube, and a coil spring transversely disposed in said tube and engaging the inner end of said hook. Y

9. In a loom, apattern chain, a supporting tube, a spool bearing bracket secured thereto, -a substantially rigid chain-engaging hook pivotally mounted on said bracket and extending within the tube, and means to force saidl hook yieldingly outward.

In testimony whereof I have hereunto affixed my signature.
